If I already have sparse data loaded in memory as a list-of-list, how can I construct a table using it?for example, givend = [['a', 'b'], ['e', 'f', 'g']]how to create table something like:data = Orange.data.Table(d)

I know I can create a basket file that contains:a, be, f, g

and create a table using it:data = Orange.data.Table('mydata.basket')

however, I would like to create the table directly from memory without using a file. how can i do that?thanks.
